The two long hooked reefs off Northwest Point caught both the U.S. brig Chippewa (in 1816) and the U.S. schooner Onkahye (in 1848). This area is well known as a ship "trap" and has claimed dozens of ships over the centuries. By the time navigators realized they had made a mistake, the prevailing easterly wind and waves made it nearly impossible to escape. Image courtesy of Google Earth.
